Hi Rooters, Suppose I run supplied macro 'shapes.C'. In OpenGL view: - typing 'j' which should result in drawing objects farther away, actually results in their gradual disappearance (I'd say it looks like shapes are being immersed in some opaque liquid, like milk in this case, since the background is white) - typing 'k' gradually restores original view but at certain point objects do not move any closer, while I wanted to go between or inside them. It looks like the view is restricted by some boundaries which are probably (guess) in the case of 'shapes.C' are defined by the dimensions of the 'node1' which contains all the other nodes. Here is the question, if it is possile at all to move shapes so that the viewer can see them from the inside? May be someone has workaround? Next question - is it possible to introduce interactive manipulation of the shape's transparency? (I understand that OpenGL allows to do so). Or at least change the view to hardcoded 'predefined' transparent mode by pushing some button. People use ROOT as an EventDispaly tool rather efficiently. OpenGL allows to get views of 'stunning beauty', to add some functionality to this beauty I think moving 'inside' detector and have the ability to look at tracks/hits through a bulk of the detector are the options which everyone would certainly appreciate. regards, Dmitri Litvintsev /----------------------------------------------------------\ | Tel: (630) 840 3763 | | FAX: (630) 840 2968 | | office: 164-O CDF Trailers | | E-mail: litvinse@fnal.gov | \----------------------------------------------------------/
